Question

I have my Firefox setup to "never remember history" and "tell websites i do not want to be tracked," so when i close my browser it logs me out of email or anything else I'm logged into and clears everything. After some use when I exit the browser and come back later my email login will start to save when i do not want it to. I have tried several times to "reset Firefox" and it works temporarily but eventually reverts back to saving that information. I have also gone into the config page and set the security and privacy to level 2 (cannot find the link now on how I got that now).

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.

After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).

Delete the Firefox installation folder, which is located in one of these locations, by default:

Windows:

C:\Program Files\Mozilla Firefox

C:\Program Files (x86)\Mozilla Firefox

Mac: Delete Firefox from the Applications folder.

Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.

Now, go ahead and reinstall Firefox:

Double-click the downloaded installation file and go through the steps of the installation wizard.

Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
